GOMPOUND APPLIANCE.

My present invention has to do with compound appliances or tools, and contemplates the provision of a compound app iance adapted with the use of interchangeable attachment to be used to advantage as a valve lifter in automobile repairwork, a valvespring compressor, and a piston-ring contractor.

The invention also contemplates the provision of a tool or appliance so characterized that the operator is enabled to exert great pull or pressure with the expenditure of but little effort.

To the attainment of the foregoing, the invention consists in the improvement as hereinafter described and definitely claimed.

In the accompanying drawings, forming part of this specification Fig. 1 is a side elevation illustrating `the preferred embodiment of my invention equipped for use as a valve-spring compressor;

Fig. 2 is a similar view showing the deviced equipped as a valve lifter;

Fig. 3 is a side elevation showing the appliance equipped for use as a piston-ring contractor or squeezer;

Figs. 4 and 5 are perspectives illustrative of the jaws employedrwhenvthe device is to be used as a valve-spring compresser;

Fig. 6 is a fragmentary or det-ail view taken at right angles to Figs. 1, 2,-and 3, and showing the keeper member of the appliance; i

Figure 7 is a detail fragmentaryperspective showing one end of the piston-ring contracting or squeezing means; and Y Figs. 8 and 9 are detail perspectives of the jaws for use when the devi-ce is to be used as a valve lifter. .Y

Similar numerals designate correspond- Y ing parts in Figs. l, 2, 3,'and 6, to which reference will first be made.

Among other elements my novel appliance comprises a body bar and a pressure bar 2, the said bars 1 and 2 beingr pivotally connected together at 3, and the bar 1 being equipped adjacent to its heel end with a pivoted keeper member 4 having cross-bars 5 at intervals in its length. The heel end of the pressure bar 2 is headed as designated by 5 for convenient detachable engagement of the saniewvith the cross-bars 5 of the keeper member 4. It will also be Application led May 12, 1926.

Serial No. 108,680.

noted that the pressure bar 2 is provided at an intermediate point in its length with an arcuate portion 6. Pivotally and detachably connected at 7 to the body bar l is an arm 8 for cooperation with the pressure bar 2, the said arm S being adapted in one use of the appliance to receive the arcuate portion 6 of the pressure bar 2, and being equipped with spaced antifriction rollers 9 adapted in said use of the appliance to rest at the opposite sides of the arcuate portion 6 of the pressure bar. The pivotal connection of the pressure bar 2 to the body bar 1 is effected through the medium of a removable pintle or boltk3, and in order to preclude casual displacement of the said pintle, 3 I remploy'a rspring 10 detachably associated with the pin 3 and adapted to serve the Vsame general purpose as a cotter pin. The forward end of the body bar l and arm 8 are bifurcated, and near their forwardends the body bar 1 and arn'iS are provided with removable bolts 11 and 12. The bifurcations alluded to are designed for the reception o-f the shanks of` jaws land 14 and also for the reception of the Shanks of jaws 15 and 16 as well as for thereceptibn of the shanks of j aw-like members 17 and 18. The said jaws and jaw-like members being adapted to be used interchangeably as hereinafter described.

By particular reference to Figs. 1, 4 and 5, it will be understood that the jaws 13 and 14 designed lfor use when the appliance is to be employed to compress a valve spring or constructed as best shown in Figs. 4 and 5-i. e., the jaw 13 is provided with inwardly-directed spring engaging portions 13X, and the jaw 14 is provided with inwardlydirected spring engaging portions 14X, the portions 13` being arranged above side walls 13Z and the port-ions. 14 being arranged below side walls '142. Manifestly constructed as described, the jaws 13 and 14 may be depended upon to take secure hold of a spring to be compressed. The jaws 15 and 16 for valve-lifting purposes are shaped as best shown in Figs. 8 and 9, the jaw 15 having inwardlyk directed portions 15 at the lower edges of side walls 15b, and the jaw 16 having spaced arms 16a so that said jaws may be expeditiously and easily engaged with a valve to be lifted.

By comparison of Figs. 1 and 2, it will be readily understood that for valve-spring compressing purpose the pressure bar 2 will be relatively arranged as shown in Fig. 1, While for valve lifting purposes, the pressure bar 2 Will be relatively arranged as shown in Fig. 2. Manifestly in each of the said arrangements the user of the appliance is enabled through the medium of the same to exert great power and this with the eX- penditure of but little effort; and it Will also be manifest that after the positioning of the pressure bar 2 as desired, the said bar 2 may be detachably loclred or fastened in position by engaging the end 5X of the same With the keeper member 5.

The jaW-lile members 17 and 18 of the piston-ring squeezing or contracting means are pivotally connected to plates 19, and the said plates 19 are riveted or otherwise {X- edly secured to a band 20 adapted to take about a piston ring and having lapped portions 21, Fig. 3. Vhen the appliance is to be used to contract or squeeze a piston ring, the band 20 is arranged about the piston ring, and the Working parts of the appliance are relativelv arranged as shown in Fig. 3, and the contraction or squeezing of the piston ring is brought about by the movement of the pressure bar 2 toward the body bar 1.

The forward ends of the body bar 1 and arm 8 are bifurcated as designated by 22, and the said jaws and jawlile members are provided With lateral projections 23 adapted to take into the said bifurcations 22. By virtue of this provision it Will be understood that When the jaws or jaw-like members Which are bifurcated at their ends as designated by 211 are arranged in engagement with the bolts 11 and 12, the jaWs and jawlike members will be securely held to the body bar 1 and arm 8; and it Will be noticed in this connection that it is not necessary for the bolts 11 and 12 to be removable. On the other hand, the jaws and atvlike members are simply moved rectilinearly into and out of engagement With the body bar 1 and the arm 8.

It Will be apparent from the foregoing that notwithstanding the capacity of-function ascribed to my novel compound appliance, the appliance is simple and inexpensive in construction, is Well adapted to Withstand the usage to Which automobile tools and appliances are ordinarily subjected, and is highly efficientin .each of the,uses for which it is adapted.
